Completion of an audit loop assessing vestibular schwannoma screening pract
ice in a sub-regional ENT centre shows good agreement between the guideline
s given and indications used for selecting patients to undergo screening MR
Ig. The proportion of cerebellopontine angle tumours diagnosed is consisten
t with other reports from the United Kingdom. During the audit period the p
roportion of patients screened because of unilateral tinnitus increased, bu
t not beyond a reasonable estimate of the proportion that could expect to b
e screened because of this symptom. There was a reduction in the number of
inappropriate scan requests after introduction of a guideline reminder. Dur
ing the initial period after introducing screening guidelines there is incr
eased screening activity, but this plateaus at a steady level.
